> When have you seen a movie about the USSR winning the WW2? Any Russian movies about the US winning the WW2? Naturally each country tells their own narrative. This seems like a silly point to make.
It's not a silly point to make when you realize that Hollywood is not a government agency. It is a reasonable question to ask how this coordination is possible when there are no legal restraints on failing to coordinate.
The simplest explanation is that, especially historically, Hollywood has targeted domestic audiences first. What message do you think is/was more likely to play well in the US and broadly in the west?
